ELEVATOR SIGNALING APPARATUS.

Specification of Letters Patent.

Patented April 16,1907.

Application filed mm 80, 1906. Serial No. 324,209.

To all whom itmay concern.-

Be it known that I, JOHN D. BowNE, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Elevator Signaling Apparatus, of which. the following is a specification.

My invention relates to elevator signaling apparatus, and it belongs to that class of electromechanical contrivances which are de signed for use in connection with a lurality of elevators operating usually in s afts arranged side by side or near each other.

My invention is comprehended also in-that class provided with up and down signaling means, whereby an intending passenger may from any floor at either .shaftdoor on such floor cause to be-given a suitable si nal in that elevator-car nearest the certain oor at,

the time and proceeding in the direction desired.

The object of my invention is the production of electrically-operated signaling mam chinery possessin the functions stated and embodying detai s of special construction and particular arrangement for carrying out those functions and in addition thereto for enabling any elevator-car to be out out or freed for the time being of its operative relations with the signaling system in order that it may be run express -that is to say, the car may travel from a low' to a high floor without being signaled intermediately.

I accomplish the objects mentioned by fashioning and associating parts as illustrated 'n the accompanying drawings,- of which Figure 1. represents a front view of an installation comprising three elevators and shafts, with thoseportions ofthe mechanism constituting my. invention somewhat exagerated in size to show them more clearly.

ig. 2 is a side view ofone set. of magnets.

pertaining to one elevator and relating, for example, to the up-signal for one floor and one elevator. Fig. 3 is a side view of the same set of magnets appearing in Fig. 2 ,but the view is taken from the opposite side to show the magnets relating to a down 'signal from the same floor.

front'wall removed to exhibit the cut-out Fig. 4 is a front view of one of the miniature elevators with itsJnurnber' 21.

ature elevator related to middle ear: 5 are solenoid carriedwithin it. Fig. 5 is a top plan view of all of the miniature elevators and the signaleresetting devices located in position to be actuated by their movements. Fig. 6 is an explanatory and fragmentary erspective view of one of the circuit-making orks and shows the magnets, .which when successively energized permit the fall of the fork and the making of. the signaling-circuit.

In all figures after Fig. 1 the scale of draw-' ing has been increased.

Like numbers are used to refer to the same parts throughout the description and drawin s.

n Fig. 1 there are shown any three floors of a building above the lowest floor. One floor is designated by numeral 1, the second higher floor by 2, and the third floor by numeral 3. -Three elevator-cars (marked 4., 5, and 6) serv those floors in suitable shafts arranged si eby side. Upon each floor the door of each elevator-shaft is provided with two signaling devices-for example, pushbuttons, conveniently placed. At each door one'of such push-buttons is to be operated by an intending 'assenger desiring to go up and the other pus i-button by a person seeking to go to a lower floor. On all the floors-for elevator ithe rip-signal push-buttons are referred to by numbers 7 and the down si nal pushbutton by number 8. For the mi dle elevator 5 on all floors the up'push-buttons are marked 9 and the down push-buttons 10. For the ri htd and' elevator 6 on all floors the up'pus li-buttons are designated 11 and "the\d'own push-buttons 12. The various push-buttons will be again referred to.

On the staging 13 above the top floorin this instance the third floor 3--are supported the customary sheaves 14, 15, and 16, with their individual shafts 17 18 19. On the top floor 3 or upon a suitable adjacent platform.-

are erected vertical ways or rails in pairs for the guidance of the miniature or auxiliary elevator-cars forming a part of my invention. There are as many miniature elevators as there are full-size elevators, and they are re lated to each other as explained below. The ways of the miniature elevator corresponding with car 4 are designated'by numberv 20, and the miniature car therein isreferred to by Similarly the ways of the minimarked 22, and the miniature car in them is designated 23. Again, the ways of the miniature elevator actuated with right-hand car 6 'are denoted by numbers 24, and the miniature car adapted to run in them bears the reference-number 25. In addition to the usual cables by which it is raised and lowered each large elevator is connected-with one endof one of three conducting-cables 26, 27, and 28, by which the electric current is transmitted to operate the different magnets. and

- solenoids.

At one side of the ways for the miniature elevators are arranged the electromechanical and electromagnetic contrivances by which j the signals are operated. Such contrivances are employedin sets or units.

. in all nine units, as illustrated in Fig. 1. The

" car.

tion of one unit which is engaged, let it be as-'.

unit of mechanism mentioned is best exhibited by Figs. 2, 3, 5, and 6.v Each unit comprises a passengeroperated magnet 29*in other words, a magnet energized when a pas.- senger presses the corresponding push-buttonand a car-operated magnet 30that is to say, the magnet 30 is energized by a current in an independent circuit made by. devices borne by and moving with a miniature Those two magnets constitute the porsuined for purposes of this description, when the person signaling desires to go up. To complete the unit of mechanism, two more magnets (designated 31 and 32) of like structure and function are introduced to effect the signal sought to be given by a person intending to go downward. As the operation and results of the operation of the up-signal mag nets 2S) and 30 and their accessories are in all respects substantially identical with those of the down-signal magnets 31 and 32, it is believed to be suilicient to limit this explanation to the up ignal magnets and relatedele ments. The armatures of the magnets 29 and 30are the tilting angle-pieces 33 and 34,

individually movable upon the rod 35. The horizontally-projecting portions 36 and 37 of the armatures are counterbalances, and when the-magnets are dead the two armatures rest in their normal attitudes off from the cores, as delineated in Fig. 6. To positively limit the play of the armatures 33 and 34, posts 38 and 39 are adjaeently disposed, and headed screws 40 pass through-jam-nuts 41 into the. os'ts. The horizontal portions 36 and 37 of the arn'iatures strike the head and nut, and their tilting movements are thereby adjustabl limited.

In Fig. 6 it willbeobserved that a rocking bar 42 rests with its opposite ends on the ing shaft 56. 'the counterweighted arm 57. weight of the arm is marked 58, and the hub tops of the armatures 33 and 34 and that the rocking bar is. pivotally secured at its middle point by pin43 between the cars 44, which project downwardly from 'the shank 45 of a pivotal electric switch-armthat I have termed in' this description the fork. By reason of its stated support upon the upper edges of armatures 33 and 34 the rocking bar 42 bears the weight of the fork, and were it not so supported the fork would fall and dip its prongs 46 into the mercury 47 contained in the cups 48 and 49, to be again mentioned. The prongs 46 are' the end portions of a U-shaped piece of copper held between strips of insulation 50 in the.- jaws 51 with which the outermost end of thefork 45 is provided. The butt of thefork is formed into a transverse cylindrical end 52, bored to fit and movably carried on the forks rod 53. It is believed to be clear that if the prong-bearing end of the fork falls. the finger 54, projecting downwardly from the cylindrical end 52 of the fork, will be turned correspondinglythat is to say, finger 54 turns toward the cam 55 on the long rock- Long rocking shaft 56 carries The counterthrough which shaft 56 passes movably is designated by number 59. In Fig. 2 it is shown that the hub of arm 57 has a slot/60, and. a pin 61 passes through the slot into the shaft. The engagement of the pin and slot is such that when the arm 57 is normally. held horizontal by counter weight 58 its inner end 62 may-be forced downwardly without turning the shaft. If,

however, the end 62 of the armis raised, the pin meets the end' of the slotiand shaft 56-is' turned accordingly.

As previously stated, the parts above described relate to theup-signal magnets 29v and 30. The down-signal magnets 31 and 32 are correlated with elements of the same number, size, and function, of which the fork is designated by number 63, thelong rock; shaft corresponding to shaft 56 is marked 64, and the counterweighted arm is referred to by number .65. For the down-signal m agnetsithe arm 65, while possessing in its hub the slot 66, engaging pin 67, secured in shaft 64, has those parts so arranged, as appears in Fig. 2, that the end of the arm may be turned up without rocking the shaft, which is rocked when the arm is turned down wardly. In orderthat the pin 67 may normally engage the lower end of the slot 66 and cause arm 65 to come to rest promptly in its approximately horizontal position, it is obviously necessary that. the portion of the arm having the flattened end shall be the heavier part. To effect this variance in wright of the two portions of arm 65 and still preserve the desired uniformity of appearance of all the arms 62 and 65, any designers expedient i may be-employed-as, for example, by making the a parently weighted portions of arm 65 hol ow.

The vertical posts or 'rods by which the units of electromechanism are adjustably supported-are marked 68, and upon the front rods 68 will be noted the sleeves 69, having the set-screws 70, enabling them to be fixed higher or'lower on therods. Sleeves 69 ro have inwardly-projecting arms or lugs .71, in which is secured the horizontal rod 72, which also passes through the eyes of the "brackets 73, that carry the table or plate 74, upon which are the mercury-cups 48 and 49 before mentioned.

The two horizontal shafts described as long rocking shafts 56 and 64 are'journaled in the projecting portions 75 and 76 of sleeves 77 and 78, attached by set-screws to rear rods 68, thosesleeves being of the same form as'sleeves 69.

Considerin Fig. 1, it will benoted that the chains or cab les 79, 80 ,and 81, by which the miniature elevators are raised and lowered, are operated by the shafts of the sheaves. The movement up or down of each miniature elevator is therefore very much less in extent and speed thanthat of the large'car. It -may befstated, consequently, that while the v s'ojmin'iature: elevator-cars carry certain pro- Lecting devices intended to strike other parts eld stationary upon the supports the blows delivered are in-no sense violent or destructive, owing to the relatively slow'movement of the minlature cars.

Fig. 4 discloses the interior of one of the miniature carsfor example, car 25 on the right of the three described. The solenoid contained within the car is designated by 4 number 82 and its movable core by the numher A current passing through the coils of the solenoid would obviously draw the core 83 into it against the force of the spring 84, that is shown encircling the upper end of the core'between the washer 85 and the top of the miniature car. The reaction of spring 84 withdraws the core when the current is broken. Above and below the solenoid pins 86 and 87 projectfrom the core and engage 5 slots 88 and89 in arms 90 and 91. Arm 90 has one end secured to the short rocking shaft 92, that passes through one side of the miniature car, and arm 91 has one end secured to a like short rocking shaft 93, passing throu h the opposite side of the car. Outside of the car the shaft 92 carries fixed upon it the crank-arm 94, and a similar crank-arm 95 is attached to the shaft 93 also on the out- I side of the car. The up er end of the crankarm 94 is provided wltlithe outwardly-projecting pintl'e 96, and the crank-arm 95jhas at its upper end a like pintle 97.

In Fig. 2 it willbenowseen that the pintle '96 is dlrectlvfinder thefinner end 62 of the 5 counter'weighted arin 1. 57 and, -bearing in .the lower portion of arm 95.

mind the precedingexplanation, if the miniature car 215 is raised the pintle 96 will encounter the end 62 ofthe arm 57 and rock the shaft 56, thereby turning the cam 55 toward the downwardly-extending. finger 54 of that fork described as being related to the upsignal magnets. The pintle' 97 of crankarm 95 carries a laterally-projecting pivoted strike or tappet 98,'and a spiral spring 99 has one end attached to the strike and one end to 7 5 The spring 99 is constructed to yieldingly hold the strike horizontally and to return it to that position when displaced either way by contact with another part. The crank-arm 94 carries upon its pintle 96 a strike 100' of the same nature and construction as strike 98 with the exception that strike 98 has secured to it upon its upper side a strip of insulation 101 while the strike 100 bears alike piece of insu- 'lation 102 upon its under edge or side. The

spiral spring 103, having one end attached to' strike 100 and one end to the lower portion of the crank-arm 94, is a twin in structure and operation with the spring 99. 'In Fig. 4 will also be noted the adjustable sleeve 104, held by its set-screw upon one of the rear rods 68. The sleeve is composed of'insulation and is'provided with a projecting pin of metal 105. The pin 105 is, as shown, directly in the path ofthe strike asthe miniature car is raised.

Returnin to Fig. 1, attention is now called to the switches 106, each large car having one conveniently placed. The switch illustrated 100 is in car 6, and the conductors 107 from it include a battery 108 or other source of electricity. Those conductors form a part of the cable 28, leading from that car. In Fi 1. are also shown'the three conducting-cables 109, 110, and 111, which, with the like cables 26,. 27, and 28, connect each of-the switches 106 in the large elevator-cars with the solenoids 82, contained within the miniature ears. The ends of cable 111 are shown conno nected to the binding-posts 1 12' on the miniature elevator 25, and the ends of the solenoid are likewise led to those posts. The remaining features of my invention will be described in connection with the ex- I r 5 planation of the mode of o eration. In the usual way a'conductor 113 1s common to the circuits of both of any pair of ush-buttons for example, in connection wilih push-buttons I 11 and 12 on floor 1 and relating to large ele- 12o vator 6.' The complementary conductor for the u signal ush-button 11 is marked 114 and t at for t 1e dowipsignal push-button '12 has the reference-number 11 5. Those conductors are arranged, the common conductor 1 2 5 113 including the battery 116, and are suitably connected to enable an intending pass senger who presses the up-si nal ush-button to GDGIgLZGOD the same oor-a lthe u signal magnets 29'before mentioned as t e- 0 passenger-operated magnets of the pairs of up-signal magnets. Each armature 33 is now attracted and moves toward the core of the magnet and from beneath one end of the rocking bar 42, which it had supported. The rocking bar has been describe as pivoted in the middle. Therefore the unsupported end drops slightly. It may be noted ere, as appears in F igs. 4 and 6, that the dro of the ends of the rocking bars is limitei by the lugs 117 118, projecting from the sides of each of theforks 45. The dropping of the ends of the rocking bars is all the imQ mediate result of the actuation of the pushbutton, and each fork is, under the circum stances, supported only by the end of the rocking'bar that is still resting on top of armature 34 of the companion magnet .30.

It will be understood that by reason of the fact that log 117 of fork 45 prevents any but a certain inclination of the rocking bar with respect to the fork the end of the rocking bar still sup orted carries the weight of the fork. To effect the desired signal, a magnet 30 must be energized. The necessary circuit, termed herein the independent circuit, composed of the conductors 119, including a battery 120. is completed by the operation of miniature elevator 25. The strike 1.00 as the car rises. comes into contact with metal pin 105 of insulated sleeve 104. The conductor being connected with the pin, and the miniature car being necessarily grounded by its metallic connection with the remaining machinery, the current flows through the coil of magnet 30 again to ground, whereby armature 34 is attracted and. the rocking bar 42 robbed of its last support The fork falls and the prongs 46 may be thus eonstituted the bond to complete two circuits, one of which, composed of conductors 121, battery 122, or other source of electricity, includes a 'red light 123, located above the door of the right-handelevator shaft upon the floor where the passenger waits, indicating .to him that the nearest elevator going up is in the shaft at which he is standing. The second circuit-completed by the prong'is composed of conductors 124 and suitable battery and is comprised in the cable ofconductors 28 with which car 6 is provided. Co1iductors 124 constitute the indicator-circuit, and they lead from the indicator in the car to the electromagnetic units related to'the car 6 and corresponding to floor 1, asshown in Fig. 1. There are twice as many indicator-circuits for the same elevator as there arejloors, excepting the very highest and lowest floors, because. there are two units for each elevator for each floor, one unit to effect the up-signal and one unit to bring about the dorm-signal.

It is my practice to furnish each car with an indicator 125, having acolored light and a white light arranged side by side foreach floor. The colored light is to signify that an lip-going passenger is waiting at the floor indicated and a white light for the opposite direction. A colored light would therefore be made to glow in the car '6, indicating the signaling-floor, and it would continue to glow until the pintlc 97 of the crank-arm rises against the end 62 of the counterweighted arm 57 and rocks the shaft 56, bringing cam 55 of the shaft against finger 5 1 of the fork, thus lifting prongs 46 out of the mercury and breaking both indicating-lamp circuits mentioned, at the same time permitting armatures 33 and 34. of the magnets 29 and 30 to resume their original positions and to receive and support the ends of the rocking bar, 42 upon their upper edges. The contact of the pintle 97 and the end of the counterweighted arm-57 is of short duration, as the arm turns up and the pintle rises away from it. Such escapement permits the fork to drop, but the armatures are already in place to catch the descending rocking bar. It is thought to be clear from the foregoing that the indicator-lamps may be lighted in the car some time before the car reaches the floor if the contactpin is placed low enough on rod 68. Furthermore, the lamps may be kept glowing for a time by introducing some distance between the pin 105 and the fork-resetting counterweighted arm 57.

As stated above, the fallen prongs 16 may afford a common path for the current to light 123 and the current to the indicatdr 125. Under those circumstances the light circuit and the indicator-circuit are made sensibly the same in resistance, and the batteries are of equal strength. In Fig. 6 it is shown that there are two binding-posts 126 foreach mercury-cup 48, and the binding-- posts for each cup are connected by the strips 127 with'each other and with the mercury 47. Tw'o'binding-posts are provided for each cup as a matter of convenience in connecting up the two circuits mentioned and forthe reason that light 123 and its air cuit maybe omitted on all or on certain floors. Let itbe assumed that car6 is not the nearest approaching elevator to the intending passenger pressing the push-button at the shaft of car 6. Manifestl if another minature car belonging to anot ier elevator is to effect the polarizationof a magnet 30 and drop a fork its u rsignal unit mustbe in circuit with the pus -button. In fact, all up-slgnal units for that floor must be in 011'- ruit with it and with each of its fellow upsignal push-buttons on the same floor, as .indicated in the drawings. Each rising miniature car approaching each floor energizes one of the magnets 30 for that .floor and allows the corresponding end of one rocking bar of one fork to drop; but no signal is given unless some push-button be pressed. The

signaling operation demands the action of two magnets, yet it is unimportant which I acts first. If a miniature car has approached near enough to the level representing a particular floor to energize one ,of the magnets '30 on that floor and a person on the same iioor'then' presses a push-button, a fork will drop immediately, rectly concerned, has already allowed the other end ofrocking bar 42 to fall. While, as stated, the approach of any miniature car drops one end of one rocking bar 42 for any given floor, it will be understood that the progress of the car lifts any fallen fork for that floor and permits thefarmatures to reset 1 5 themselves in their normal rocking-bar-supporting attitudes. In Fig. 5 it is shown that the long rocking shaft 56 and its twin shaft 64 extend to all the units of electromechanism relating to the same floor, and there are as many counterweighted arms and cams on each shaft as there are elevators.

I have stated herein that each large car is prov ded with a switch 106, one of suchswitches being shown in car 6 in Fig. '1. has been explained also that the conductors .107 from the switch are comprised in the cable 28, leading from car 6, and'those conductors likewise form a part of the cable 11 1, connecting with miniature car and withthe 0 solenoid carried Within the car. When the switch 106 is closed, the current from the battery 108 passes through the solenoid, and the movable-core 82 is drawn down into it. By

reason of the engagement of the pins 86 and 87 with slots 88 and 89 in the arms 90 and 91 the short shafts 92 an d 93 are turned, causing those ends of the crank-arms 94 and 95 which have been described as provided with the. projecting pintles and the spring-held strikes to be retracted and to move inwardly and holding them, so lon as the current flows, in such positionsthat tIie. pintles willnot touch the ends of-the counterweighted'arms or the strikes encounter the conducting-pins105 as 4 5 the rniniature car 25 rises and descends. In

other 'words, the large car 6 now runs express and cannot be signaled from intermediatefloors. It has been, in fact, cut out'of r the eneral signaling system, the system being, owever, in no particular affected thereby. 'Pressure on theup-signal push-button at any door of the shaft traversed by the exj'prefss-elevator results in a signal displayed in the-nearest approaching large car going upward in either of the other shafts.

The operation of all the remaining devicesshown inthe drawings, whether for'up signals or' for down signals, being of precisely the same nature as that ijus t explained, it is 6o, thought to be unnecessary te -prolong this specification by setting out their structure and action.
